The above widget depicts weather for Chaiyaphum, however it is situated near to Koh Chang, just slightly inland. It gives a relative representation to Koh Chang weather for the next 5 days so can safely be used as a guide.
June to September are the rainy months in Koh Chang, so it is advised that you steer clear of the region during this time if possible. Your Koh Chang holidays won’t be quite as exciting if you’re stuck in the rain for most of it! Like the rest of Thailand, November to February are good months to travel, while May is also a good time to visit as it’s not quite as hot as in March and April, the hottest months of the year.
